drivers side giving me fits, passenger side works ok but will stop working suddenly. i expect the relay,(still in the engine compartment) is heating up. i just read everything available that came up in a search but was unable to find a modern, or any, replacement, for the relay. there is a small, 2wire box, about 1/2"x1" directly under and connected to the relay which could be a circuit breaker, (doesn't appear to be a fuse). i'm guessing any 20/25 amp modern cb would replace that, but i'm not an electrical guy. any help truly appreciated. thank you!
